Corba unknown exception when accessing Session bean

[Thirtha Bang]

Hi Experts,

I am running JUnit testcase called ClientTest using Ant Build tool which calls an AdminSessionBean(Session Bean) deployed on WebSphere6.1/MSSQL 2005. The purpose of running this test case is to insert some dummy rows to selected tables in underlying SQLServer 2005. Instead it is throwing the below ugly exception...have no idea what is going wrong. I also Googled it but found no information there. I would appreciate and would be thankful if anyone guide me
in fixing below issue.

java.rmi.RemoteException: CORBA UNKNOWN 0x4942fe86 Maybe; nested exception is:
